Application filed April 18,

Be it known that I, NICK WnILnn, a citizen of the United States, residing at Sioux City, in the county of IYoodbury and State of Iowa, have invented a new and useful Improvement in Swinging Stacker-s; and I do declare the following to be afull, clear, and exactdescription of the same, reference being had to the accompanying drawings,forming a part thereof. My invention relates to swinging stackers for threshing machines, and particularly to that kind which automatically swing from side to side during its operation. The object of my invention is to provide means for oper- I5 ating the stacker in this manner.

The invention consists of the mechanism for simply and automatically regulating the operation of the stacker, as will be more fully described in the claim.

In the drawings, Figure 1 is a plan view of mechanism for swinging the stacker. .Fig. 2 is a side view of rear end of thresher with the stacker shown in Fig. 1 attached. Fig. 3 is an enlarged detail View of mechanism for 5 operating the stacker shown in Fig. 1, Fig. 4 is a detail view of shaft and pinion shown in Figs. :1 and Fig. 5 is a side view of wheels and pinions shown in Figs, 1 and Fig, 6 is a detail plan view of device for operating 3 shiftingba r, is a side view-of same. Fig, 8 is an enlarged view of head of Shifting bar, Fig. 9 is a side view of the same with the d vice inclesedi L k p r s ar design d y milarletters .155 of r ference.

T is the rear end of the thresher, the carrier being operated by the chain-wheels and 6', chain 6", pulleys 6* and t", and belt t". The swinging stacker is pivotaliy secured to the 4 frame B by means of a bolt r,

U is the segment of a circle, pivotally secured to the frame at the center by means of the bolt t. The segment is ratched or oogged on its circumference and is f rmly attached to the frame t by means of a connecting-platform a. On the inner rim of the segment are provided holes r w. The segment is operated by means of a shaft a, to which is secured a worm-wheel 162, which engages the teeth of 5 the segment. At the outer end of the shaft is a sprocket-wheel a adapted to turn on the shaft and connected with the operating the thresher by a chain a.

of the sprocket-wheel is secured a wheel I65, having inside teeth or cogs and adapted to turn with the sprocket-wheel freely on the shaft. It meshes with a pinion 266, secured to the shaft '2", parallel with the shaft it. To the inner end of the shaft v is secured a cogged wheel 2", adapted to mesh with a cogged wheel n, secured to the shaft 24. The wheels if and a have hubs a and '11", respectively, the hubs facing each other and being cut out around the shaft. Between the hubs is a smooth wheel w, keyed upon the shaft, 5 as seen in Fig. 3, and adapted to slide upon it. The wheel is'provided with laterally-projecting lugs m and 20, which are adapted to engage the cut-out parts of the hubs. The wheel 10 is encircled by a loose ring w, keyed 7 upon it, as seen in Fig. 4, the wheel being adapted to revolve within the ring. Arod w" is pivoted to the ring and pivotally secured to the frame at the point M. It is then pivotally connected at right angles to a shifting bar w, having a head 70 and lugs 70 and c0. Within the head of the bar is a heart-shaped device in", pivotal] y secured to the frame. Pins :0 and :1 secured to the heart-shaped device, project upward therefrom, and a rod is, pivoted at one end to the frame, extends between the pins and over the segment. A spring a is secured at one end to the frame and at the other end to the rod 0; near its secured end. Pins 1/ and y are adapted for 5 adjustment in the holes 41 a in the segment. In Fig. 1 of the drawings the segment is shown moving from right to left. The left lug of the wheel w is shown in engagement with the hub of the wheel a, which operates the shaft a by means of the cogged wheel o shaft 2/, pinion M6, cogged wheels if, and chain-wheel a, to which the power is applied from the thresherby means of the chain a. When the pin 1 strikes the rod 0;, it will cause the heart-shaped device to turn to the left, striking the cam w and pushing the shifting bar to the left, releasing the lug w from the hub n and forcing it into the hub a7. The wheel w being keyed upon the shaft 2;, the chain- I00 wheel a now operates the shaft directly, as shown in Fig. 3, reversing the movement of the segment. The movement of reversing the segment will continue while the stacker is in operation,

Having described my invention, what I.

claim as new, and desire to secure by Letters Patent, is

In a swinging stacker, the combination of a carrier, a frame to which the carrier-is pivotally secured, a segment having teeth on its circumference and holes for the insertion of pins, a worm-Wheel adapted to engage the teeth of said segment and a shaft to which the worm-wheel is secured, a cogged Wheel secured to said shaft having a hub with a cutout portion around the shaft, a wheel at the outer end of said shaft adapted to turn freely thereon, means for imparting motion to said wheel, a wheel with inside teeth secured to said outer wheel, adapted to turn freely on said shaft and having'a hub with a cut-out portion around the shaft, said hubs facing each other, a shaft parallel with said first shaft adapted to revolve in bearings in the frame, a cogged wheel secured to one end of said shaft and site end of said second shaftand adapted to mesh with the wheel with inside teeth, a

wheel keyed to'said first shaft between said hubs and adapted to slide upon the shaft, a ring encircling said wheel, and keyed thereto, a lever pivotally secured at one end to said ring and pivotally secured near the middle to the frame, a bar pivotally secured to the opposite end of said lever,a heart-shaped deviceat the end of said bar pivotally secured to the frame and having pins extending upward therefrom, cams at the end of said bar inclosing said device, a rod pivotally secured to the frame, extending over the segment-between the pins in said device and adapted to come in contact with the pins in said segment, and a spring for holding saidrod in position, substantially as described.

In testimony whereof I have hereunto affixed my signature in the presence of two witnesses.
